I have HP DV6 1111au laptop .. with 2gb memory n 320gb HDD..Just few days back.. it started to boot on very slowly thought its working very smoothly.. I ran all the tests on HDD n memory, change the RAM, HDD.. but still the problem persists..I read a lot around about the booting process being slow but could not find any appropriate solution fot this slow boot.. The booting options also load really slow, sometimes boot time is 5 min. on main HP logo screen sometimes its .. 10-25mins.. n sometimes it cannot get started.. then I have to manually restart it.. but when if its ON when restart command being given.. it boots up rilly fast..

I have hard reset over the laptop.. changing BIOS settings.. i.e loading the default one.. also tried to update the BIOS, which is F.18 version.. no new update ...

Please help me.. all people and experts out here.. rilly .. need help...

No, thats xp! I highly doubt that the CMOS battery would stop the computer from booting. The CMOS battery powers the internal clock of the computer and that alone would not cause a complete breakdown, Maybe some errors due to the time being incorrect but NOT broken.

I was just going to say it is one of the troubleshooting questions on the A+ computer certification exam. The CMOS is required or the computer cannot boot, the battery does not just power the clock, however, without a clock the computer cannot run either. The start up settings are stored in EPROM, which is maintained by that same battery. The computer needs those setting to boot also.

. I've only run into one computer that wouldn't boot with a dead battery and that was ~15 years ago; but I don't see many computers with dead batteries. I think that happens when the HDD params get erased or scrambled (I could boot the computer if I set the drive params after the POST). Most, if not all, recent BIOSes will auto-detect the drive params, so it's not usually a problem nowadays.

i checked the battery on my multimeter, (on 6v, it doesn't hav a 3v option) and it tested out just fine (the needle was at the halfway mark) should i replace it anyways? or is there something else wrong with my laptop?

Could you desribe the symptoms prior to changing the battery? I've got a Compaq laptop of the same form factor that won't boot into Windows. I had also suspected a bad mobo so thanks for this suggestion, I'll give it a try...

mine looks just like yours, the battery is different though, it has wires coming off of it onto the mobo. hopefully (since compaq and hp are one and the same) this will work. i have wanted a laptop for as long as i can remember. wish me luck!

A friend of mine gave me the laptop because he went to the Computer shop and they asked 400€ to repair it. He gave it to me. The symptoms were that the power button was flashing, and no signal on the screen and no boot. I changed the battery and everything worked fine =)

Thanks for your reply I just made this instructable because I was wondered when I saw that it works For me it worked great,so just try it before cast it And it is XP,but I saw that the HP G5000 is compatible with Kalyway,so maybe i'm gonna to change And please,rate it
